Alexis definitely looks physically built for the Premier League. A player who has a real burst pace and dribbling abilities, physically strong and can score a few goals would make for one of the best wingers in the league. Pedro, under van Gaal would work, imo. Nowhere near as physically strong, nor technically gifted, but his reading of the play and movement would make him a menace down the right wing. He is lighting quick and is very clinical, put him in on goal and he'd find the net 9 times out of 10. An outlet in a possessive based system (as shown under Barcelona) is what is needed.
